Agrion macrogaster Selys from Jamaica has been placed in the genera Nehalennia, Leptobasis, and Telebasis. In 1960 the author reared it from bromeliads in Jamaica and found the larva so unique that the new genus Diceratobasis Kennedy (1920, Ohio J. Sci. 21: 83-88) was accepted for it. Christiansen (1947, Psyche 54: 256-262) described a new genus and species, Phylolestes ethelae, from Haiti and suggested it might belong to the Synlestidae, with its nearest relative in Africa. Larvae which the author collected in 1960 proved him correct. The larvae of both species are herein described.
